BACKGROUND

The present invention relates generally to the field of machine learning, and more particularly to utilizing machine learning to detect interaction during a meeting.

Online meetings, also referred to as web conferencing and video conferencing, began in the 1970s and greatly increased in the 1980s with the computer revolution and rapid growth of the internet. Video conferencing is a cost-effective solution today for holding business meetings with people in multiple locations (i.e., physical spaces), by reducing the need for business travel expenses such as hotel and airfares.

DETAILED DESCRIPTION

Embodiments in accordance with the present invention detect and synchronously track one or more participants in a room, or set of rooms, with video and audio streams, and then use that set of simultaneous information streams to enhance highly dynamic meeting settings and to make the meetings much more interactive, transparent, effective, and productive.

Existing meeting analysis approaches analyze raw audio-visual streams from meetings and use results of the analysis to provide meeting summaries or to answer questions during or after the meeting, such as: What has been said during the meeting? What events and keywords occur in the meeting? Who and where are the persons in the meeting? Who in the meeting is acting or speaking? How do people act in the meeting? What are the participants' emotions in the meeting? Where or what is the focus of attention in meetings?

However, existing approaches do not take audio visual streams from a set of locations and combine them to create a rich, unified representation of the meeting incorporating the emotive states of the participants, the participants' agreement or disagreement on topics that have been raised during the meeting, a participant's reactions to other participants, and so on. Furthermore, the data from audio-visual streams is typically not combined with data such as meeting schedules, room states, and screen states to facilitate coordination and set-up of a physical and on-line meeting space across multiple meetings and long-running activities (activities that might intermittently make use of the meeting space over several weeks of months).

Embodiments in accordance with the present invention help remote and local participants feel more connected to a physical meeting. Certain things are easily perceived in person (emotion, agreement or disagreement, and whether people are attending to what is being presented) but are hard to tell if you are remote or across the room. It can also be difficult to get a global or summary view of this information for many locations. With the right information, however, people can make interactions that have more of an emotional connection, and can be more persuasive, and more engaging. Embodiments in accordance with the present invention provide methods of detecting and tracking participation in a meeting and generating interventions to improve the participation by utilizing one or more sensors in a physical and remote environment to detect emotional, attentional, and dispositional states. A unified meeting representation is maintained, and interventions are delivered using avatars.

Embodiments in accordance with the present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram, generally designated 100, illustrating a remote meeting environment, in an embodiment in accordance with the present invention.

Remote meeting environment 100 includes server 102, computer 118, and other computing devices (not shown), all interconnected over network 116. Server 102 includes random access memory (RAM) 104, central processing unit (CPU) 106, persistent storage 108, and user interface 110. Server 102 may be a Web server, or any other electronic device or computing system, capable of processing program instructions and receiving and sending data. In some embodiments, server 102 may be a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating over a data connection to network 116. In other embodiments, server 102 may represent server computing systems utilizing multiple computers as a server system, such as in a distributed computing environment. In general, server 102 is representative of any electronic device or combinations of electronic devices capable of executing machine-readable program instructions and communicating with computer 118 via network 116 and with various components and devices (not shown) within remote meeting environment 100.

Server 102 includes persistent storage 108. Persistent storage 108 may, for example, be a hard disk drive. Alternatively, or in addition to a magnetic hard disk drive, persistent storage 108 may include a solid state hard drive, a semiconductor storage device, read-only memory (ROM), erasable programmable read-only memory (EPROM), flash memory, or any other computer readable storage medium that is capable of storing program instructions or digital information.

Server 102 includes user interface 110. User interface 110 is a program that provides an interface between a user of server 102 and a plurality of applications that reside on server 102 (e.g., meeting software 114) and/or may be accessed over network 116. A user interface, such as user interface 110, refers to the information (e.g., graphic, text, sound) that a program presents to a user and the control sequences the user employs to control the program. A variety of types of user interfaces exist. In one embodiment, user interface 110 is a graphical user interface. A graphical user interface (GUI) is a type of interface that allows users to interact with peripheral devices (i.e., external computer hardware that provides input and output for a computing device, such as a keyboard and mouse) through graphical icons and visual indicators as opposed to text-based interfaces, typed command labels, or text navigation. The actions in GUIs are often performed through direct manipulation of the graphical elements. User interface 110 sends and receives information through meeting software 114 to computer 118. Server 102 may include internal and external hardware components, as depicted and described in further detail with respect to FIG. 10.

Operating system 112 and meeting software 114 are stored in persistent storage 108. Operating system 112 enables server 102 to communicate with computer 118 and other computing devices (not shown) of remote meeting environment 100 over a data connection on network 116. Meeting software 114 enables server 102 to mine streams of video and audio, using machine learning algorithms, to identify, isolate and tag individuals, within a room or set of rooms and use those simultaneous video and audio streams, again using machine learning algorithms, to estimate state defined as: body or body component movement, gesture, eye movement/gaze and pupil dilation, pulse rate, and via infra-red (IR), body heat, as well as individual and group dynamics/interaction. In addition, the algorithms are used to infer such things as individual and group emotion, meaning of gestures, eye movement/gaze/pupil dilation and use body heat and pulse rate as additional information sources and confirmation sources. Over a short period, the room(s) use machine learning algorithms to learn the behaviors of specific individuals and of a group and provide a time synchronous stream of outputs that can be used as input or feedback to the machine learning algorithms. This includes the option of tagging to attribute semantics to video and audio, and, in some cases, may be crowd-sourced. Over a long period, meeting software 114 also uses machine learning algorithms to continuously train and learn about short-term activities, new settings, meeting types, and interactions. In other example embodiments, meeting software 114 may be one or more components of operating system 112.

In FIG. 1, network 116 is shown as the interconnecting fabric between server 102, computer 118, and with various components and devices (not shown) within remote meeting environment 100. In practice, the connection may be any viable data transport network, such as, for example, a LAN or WAN. Network 116 can be for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and include wired, wireless, or fiber optic connections. In general, network 116 can be any combination of connections and protocols that will support communications between server 102, computer 118, and with various components and devices (not shown) within remote meeting environment 100.

Computer 118 is included in remote meeting environment 100. Computer 118 includes random access memory (RAM) 120, central processing unit (CPU) 122, persistent storage 124, camera 126, and microphone 128. Computer 118 may be a Web server, or any other electronic device or computing system, capable of processing program instructions and receiving and sending data. In some embodiments, computer 118 may be a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating over a data connection to network 116. In other embodiments, computer 118 may represent server computing systems utilizing multiple computers as a server system, such as in a distributed computing environment. In general, computer 118 is representative of any electronic devices or combinations of electronic devices capable of executing machine-readable program instructions and communicating with server 102 via network 116 and with various components and devices (not shown) within remote meeting environment 100.

Computer 118 includes persistent storage 124. Persistent storage 124 may, for example, be a hard disk drive. Alternatively, or in addition to a magnetic hard disk drive, persistent storage 124 may include a solid state hard drive, a semiconductor storage device, read-only memory (ROM), erasable programmable read-only memory (EPROM), flash memory, or any other computer readable storage medium that is capable of storing program instructions or digital information. Operating system 132 and meeting software 134 are stored in persistent storage 124. Operating system 132 enables computer 118 to detect and establish a connection to communicate with server 102 and other computing devices (not shown) of remote meeting environment 100, over a data connection on network 116. Meeting software 134 enables a user of computer 118 to host a meeting in a unified meeting room with one or more additional participants and communicate with other computing devices (not shown) of remote meeting environment 100 over a data connection on network 116. Additionally, meeting software 134 can also communicate the one or more identified and tagged individuals within the room(s) and the determine state of the one or more identified and tagged individuals to the user of computer 118.

Computer 118 includes camera 126. Camera 126 enables a user of computer 118 to capture images or video streams of his/her self or the physical space surrounding the physical area of computer 118. In one example embodiment, a user of computer 118 can manually enable/disable camera 126. In other example embodiments, camera 126 can be enabled/disabled by meeting software 134. In yet another example embodiment, meeting software 114 can receive images and/or video data from camera 126 during an online meeting.

Computer 118 includes microphone 128. Microphone 128 enables a user of computer 118 to capture one or more audio streams of his/her self in the physical space surrounding the physical area of computer 118. In one example embodiment, a user of computer 118 can manually enable/disable microphone 128. In other example embodiments, microphone 128 can be enabled/disabled by meeting software 134. In yet another example embodiment, meeting software 114 can receive audio data from microphone 128 during an online meeting.

User interface 130 is included in computer 118. User interface 130 is a program that provides an interface between a user of computer 118 and a plurality of applications that reside on computer 118 (e.g., meeting software 134) and/or may be accessed over network 116. A user interface, such as user interface 130, refers to the information (e.g., graphic, text, sound) that a program presents to a user and the control sequences the user employs to control the program. A variety of types of user interfaces exist. In one embodiment, user interface 130 is a graphical user interface. A graphical user interface (GUI) is a type of interface that allows users to interact with peripheral devices (i.e., external computer hardware that provides input and output for a computing device, such as a keyboard and mouse) through graphical icons and visual indicators as opposed to text-based interfaces, typed command labels, or text navigation. The actions in GUIs are often performed through direct manipulation of the graphical elements. User interface 130 sends and receives information through meeting software 134 to server 102.

FIG. 2 is a flowchart, generally designated 200, depicting operational steps of a meeting software, on a server within the remote meeting environment of FIG. 1, in an embodiment in accordance with the present invention. In an example embodiment, a user is hosting an online meeting using computer 118, wherein computer 118 is connected to server 102 over a data connection on network 116.

Meeting software 114 captures interpersonal interactions between people in a physical space during a period of time, using vision and audio sensors in the physical space in order to detect the interpersonal interactions/state of each person as depicted in step 202. For example, the user hosting the meeting invites one or more participants to the online meeting. Upon joining the online meeting, meeting software 114 begins monitoring and capturing the interpersonal interactions between the one or more participants in their respective spaces (e.g., the physical spaces of the one or more participants). For example, meeting software 114 can collect data from camera 126, microphone 128, and meeting software 134 on computer 118 as well as data from the computing devices of the one or more participants, wherein the data is included in audio and video streams. In other example embodiments, meeting software 134 on computer 118 can collect the data from camera 126 and microphone 128 and transmit the data to meeting software 114 on server 102. Examples of interpersonal interactions include, but are not limited to, direct touch, a mutual gaze, a body position, a manipulation of a shared work-related object, one-on-one conversation, and a mutual gesture.

In step 204, meeting software 114 analyzes and categorizes the interactions/state and tags the state of each person over a period of time. For example, by analyzing the video stream of the meeting, meeting software 114 identifies “Rob”, “Jon” and “Danny” as currently attending the meeting, wherein “Rob”, “Jon” and “Danny” are tagged as part of the video stream. With additional analysis of the video stream, meeting software 114 can observe that Danny and Rob entered the room at about the same time, but Jon has been in the room for much of the day. From analysis of the audio portion of the video stream, or a separate audio stream of the meeting, meeting software 114 can discover that Rob is doing most of the talking with the occasional contribution by Danny, and Jon is saying nothing. In another example embodiment, meeting software 114 can detect that over the last ten previous meetings when Danny and Rob met, “Tom” was also included on the phone and had a shared on-line meeting. Meeting software 114 can then ask, via speech, or by putting up something on a screen, whether Danny and Rob would like to call Tom and set-up a meeting. If either Danny or Rob say yes, meeting software 114 can invite Tom to the current meeting or automatically set up a future meeting with “Rob”, “Jon”, “Danny”, and “Tom”. If Tom is available to join the meeting and accepts the invitation, meeting software 114 can add an additional tag for Tom to the audio and video streams.

Meeting software 114 analyzes and categorizes the interactions/state and tags the state of each person over a period of time by leveraging, and combining, the advances in vision and audio system technology with ‘short and long term’ machine learning algorithms. Short term machine learning algorithms are used by meeting software 114 to learn the behaviors of specific individuals and of a group and provide a time synchronous stream of outputs that can be used as feedback or input to the long-term machine learning algorithms. Long term machine learning algorithms are used by meeting software 114 to continuously train and learn about the short-term activities, new settings, meeting types and interactions of the meeting participants.

Meeting software 114 is able to mine audio and video streams and identify, isolate, and tag individuals, within a room or set of rooms, and use those simultaneous audio and video streams to determine one or more states for each person such as, a body or body component movement, a gesture, eye movement/gaze and pupil dilation, pulse rate, and via IR, body heat, as well as individual and group dynamics/interaction and tag those to individuals or groups. In addition, the algorithms will infer such things as individual and group emotion, meaning of gestures, eye movement/gaze/pupil dilation and use body heat and pulse rate as additional information sources and confirmation sources. For example, meeting software can determine and categorize the state of each individual as being supportive, antagonistic, and/or clarifying. Over a short period of time, meeting software 114 uses machine learning algorithms to learn the behaviors of specific individuals of a group and provide a time synchronous stream of outputs that can be used as input or feedback to the machine learning algorithms. In one example embodiment, this includes the option of tagging to attribute semantics to video and audio, and may, in some embodiments, be crowd-sourced. For example, meeting software 114, over a period of time, can tag “Tom” as being supportive to the meeting while “Rob” can be tagged as antagonistic for not agreeing on topic and “lashing out” to other meeting participants. Over a long period, meeting software 114 also uses machine learning algorithms to continuously train and learn about short term activities, new settings, meeting types and interactions.

Meeting software 114 takes an action based on the analysis of the analyzed and categorized interactions/state of the tagged individuals as depicted in step 206. For example, meeting software 114 can display the analyzed and categorized interactions/state of the tagged individuals on a screen presenting the unified meeting room with avatars that represent all of the meeting participants. In another example embodiment, meeting software 114 can present the meeting in a virtual reality environment, where participants could observe the scenes of the unified meeting room, or by using VR goggles. For example, Tom, a remote participant, would be able to see the engagement of persons in the room, if they are approving what is being said, for example by nodding, or if they are not paying attention. In this case, Tom could take actions to make sure that persons he needs engaged in a particular topic are engaged and reacting. Similarly, Jon and Rob in the meeting room would be aware of Tom's reaction and level of engagement.

FIG. 3 is an illustration, generally designated 300, of a host computer displaying avatars resembling meeting participants of a meeting, in an embodiment in accordance with the present invention. FIG. 3 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made. In an example embodiment, a user of computer 118, also referred to as host computer 118, begins hosting an online meeting where attendees can join the meeting from one or more remote locations. In the example embodiment of FIG. 3, the user of computer 118 establishes a connection to meeting software 114, on server 102, via network 116. In the example embodiment of FIG. 3, server 102 is able to host online meetings with computers 304, 306, 308, 310, 312, 314 and other computing devices (not shown) of remote meeting environment 100. Additionally, in the example embodiment of FIG. 3, computer 304, 306, 308, 310, 312, and 314 are analogous to computer 118.

Upon joining the meeting, participants are displayed on meeting attendance panel 302 with avatars that resemble each user as depicted in FIG. 3. For example, a user of computer 304 joins the online meeting and an avatar that represents the user of computer 304 is displayed on meeting attendance panel 302. In one example embodiment, the user of computer 304 can previously create an avatar to resemble his/herself and store the generated avatar on computer 304. Upon joining an online meeting, an instance of meeting software on computer 304 can transmit the stored avatar to server 102 to be displayed on meeting attendance panel 302 of computer 118. In other example embodiments, meeting software 114 on server 102 can contain user profiles for a plurality of meeting participants. New users of meeting software 114 are prompted to set up a profile and create an avatar to be displayed during online meetings.

FIGS. 4A and 4B are illustrations of a meeting attendance panel displaying the avatars of the meeting participants on the host computer, in an embodiment in accordance with the present invention. FIG. 5 is a flowchart, generally designated 500, depicting operational steps of a meeting software, on a server within the remote meeting environment of FIG. 1, for determining, and inviting, missing meeting participants, in an embodiment in accordance with the present invention. FIGS. 4A through 5 will now be discussed over the course of the following paragraphs.

Continuing with the example embodiment of FIG. 3, users of computers 304, 306, 308, 312, and 314 join the online meeting hosted by the user of computer 118 as depicted by the meeting attendance panel 302 displayed on the user interface of computer 118 and in FIG. 4A.

Meeting software 114 determines that a participant that has attended a similar meeting in the past is not present for a current meeting as depicted in step 502. For example, meeting software determines that the current meeting takes place once a week by analyzing the tags (e.g., metadata information) of a plurality of past meetings. Upon examining participant attendance of past meetings (e.g., the past ten meetings), meeting software 114 detects that user of computer 310 is not present for the current meeting and indicates the absence of user of computer 310 with a question mark on meeting attendance panel 302 as depicted in FIG. 4A. In another example embodiment, meeting software 114 can determine the missing participant by comparing the current participants to the list of required or optional meeting attendees.

In step 504, meeting software 114 prompts the host of the current meeting on whether or not to invite the missing participant. For example, meeting software 114 prompts the host (user of computer 118), using speech, or with a dialogue box displayed in the user interface of computer 118, on whether to invite user of computer 310 to the current meeting. In another example embodiment, meeting software 114 can prompt one or more of the meeting participants on whether to invite user of computer 310 to the current meeting. In other example embodiments, a user of meeting software 114, who is setting up a meeting, can define one or more delegates to serve as hosts of the meeting. For example, if meeting software asks or prompts a question to invite another participant to the meeting, any of the one or more delegates can answer.

In decision step 506, meeting software 114 determines if the missing participant should be invited. For example, meeting software 114 receive an answer from the host via the audio stream, or the host clicks “Yes” on the dialogue box displayed on user interface 130. In another example embodiment, meeting software 114 can detect the facial expressions (e.g., interpret the mouth movement), of the user of computer 118.

If meeting software 114 determines that the missing participant should be invited (“Yes” branch, decision step 506), meeting software 114 invites the missing participant to the current meeting as depicted in step 508. For example, meeting software 114 can establish a call to computer 310 over a data connection on network 116. The user of computer 310 can then accept the call or decline the call. If the user of computer 310 accepts the call, meeting software 114 can request to activate the camera and microphone of computer 310 and add an avatar resembling the user of computer 310 to meeting attendance panel 302 as depicted in FIG. 4B, and depicted in step 510.

If meeting software 114 determines that the missing participant should not be invited (“No” branch, decision step 506), meeting software 114 skips steps 508 and 510 as depicted in FIG. 5. For example, if the answer is “No”, meeting software 114 can schedule one or more future meetings based on received inputs from the host or other meeting participants. For example, the user of computer 118 can say “Yes, schedule a meeting for tomorrow at 1:00 PM with all of us”. However, the user of computer 312 interjects and says, “I have a meeting at 1:00, so I can't make it.” Upon receiving the voice inputs from the user of computer 118 and the user of computer 312, meeting software 114 can schedule a meeting for the next day at 1:00 PM with the users of computers 118, 304, 306, 308, 310, and 314.

Upon joining the meeting, meeting software 114 adds an avatar, that is representative of the participant, on meeting attendance panel 302 as depicted in step 510. For example, meeting software 114 can display the avatar of user of computer 310, stored on server 102, on meeting attendance panel 302 on user interface 130 of computer 118 as depicted in FIG. 4B. In other example embodiments, the avatars resembling the users may be stored on the respective computing device of the user. For example, upon joining the meeting, an instance of meeting software 114, executing on computer 310, can display an avatar, that is representative of the participant, on meeting attendance panel 302.

FIGS. 6A through 6C are illustrations of a meeting software recognizing emotional, dispositional, and attentional states of meeting participants, in an embodiment in accordance with the present invention. FIG. 7 is a flowchart, generally designated 700, depicting operational steps of meeting software 114, on a server within the remote meeting environment of FIG. 1, for describing a machine learning process of recognizing a plurality of emotional, dispositional, and attentional states, in an embodiment in accordance with the present invention. FIGS. 6A through 7 will now be discussed over the course of the following paragraphs.

Continuing with the previous example embodiment of FIG. 5, the host, on computer 118, is conducting an online meeting with users of computers 304, 306, 308, 310, 312, and 314. Upon starting the meeting, meeting software 114 collects audio, video, and other sensor data from multiple participants in multiple rooms as depicted in step 702. For example, meeting software 114 can gather data from one or more integrated cameras and microphones of computers 304, 306, 308, 310, 312, and 314. In another example embodiment, meeting software 114 can gather data from one or more cameras and microphones in a room that one or more meeting participants are located in. For example, if the users of computer 312 and 314 are sharing a conference room, meeting software can gather data from one or more cameras viewing the conference room and data from a speaker phone in the vicinity of the users of computers 312 and 314. In another example embodiment, meeting software 114 can determine the pulse rate (e.g., heart rate), of a meeting participant by gathering data from a BLUETOOTH enabled device worn by the user. (Note: the term “BLUETOOTH” may be subject to trademark rights in various jurisdictions throughout the world and is used here only in reference to the products or services properly denominated by the mark to the extent that such trademark rights may exist.) For example, meeting software 114 can gather data from a BLUETOOTH enabled heart rate monitor, such as a fitness device, worn by a user, wherein meeting software can determine a pulse rate of the user at a specific moment in the audio and video stream. In yet another example embodiment, meeting software 114 can detect emotional states of meeting participants by monitoring Infrared (IR) body heat patterns of one or more meeting participants during the online meeting. For example, meeting software 114 can use one or more cameras (e.g., such as camera 126, or cameras located in the same space as the one or more meeting participants), to detect one or more emotional states of the one or more meeting participants. Examples of detectable emotional states include, but not limited to, the following: anger, fear, disgust, happiness, sadness, feeling neutral, anxious, love, depression, contempt, pride, shame, and envy.

In step 704, meeting software 114 analyzes the data to recognize and identify emotional, and dispositional states of the multiple participants. For example, meeting software 114 analyzes data of the one or more meeting participants using the audio and video streams, one or more BLUETOOTH enabled devices, such as fitness devices, and one or more IR cameras (not shown). In analyzing the audio streams of the meeting participants, meeting software 114 can recognize and identify the pitch and tone of a meeting participant objecting to a comment spoken by another participant. At the same time, in analyzing the video streams of the meeting participants, meeting software 114 can recognize and identify movement, and gestures of the same meeting participant that objects to the comment spoken by another participant. Additionally, for the same meeting participant, meeting software 114 can recognize an increase in the heart rate of the meeting participant that objects to the comment spoken by another participant. Furthermore, in analyzing the IR data, meeting software 114 can recognize and identify the body heat of the same meeting participant that objects to the comment spoken by another participant, and identify that meeting participant as being angry.

Meeting software 114 isolates and tags individuals of the identified emotional, and dispositional states in the audio and video streams as depicted in step 706. For example, meeting software 114 can tag the analyzed data to identify the particular individual at certain periods of time during the online meeting. For example, during the online meeting, the user of computer 306 becomes distracted by work and begins typing on a keyboard and not contributing to the discussion as depicted in FIG. 6A. Meeting software 114 identifies the sound of the keyboard from that audio stream data from computer 306. Additionally, meeting software 114 identifies the hand movements and gestures of the user of computer 306 with the hand movements and gestures used in typing on a computer keyboard. Furthermore, meeting software 114 identifies the body heat pattern, or signature of the user of computer 306, as neutral and not the same as the other meeting participants who are actively participating in the online meeting. Meeting software 114 then tags the audio, video, and IR data streams at that moment in time to identify user of computer 306 as typing and not contributing to the meeting.

In another example embodiment, the user of computer 304 begins to participate less frequently and eventually begins to fall asleep as depicted in FIG. 6B. In analyzing the audio stream data of the online meeting, meeting software 114 determines that the participation level (e.g., the number of times the user of computer 304 speaks), has become less frequent over a period of time. Additionally, in analyzing the video stream data from the online meeting, meeting software 114 detects that the head of the user of computer 304 is bobbing periodically and the user's eyes are closed. In addition to analyzing the audio and video data, meeting software 114 analyzes data from a BLUETOOTH enabled fitness device worn by the user of computer 304 and determines that the heart rate of the user of computer 304 is 42 beats per minute, which is the same heart rate measured for the user of computer 304 during sleep periods. Meeting software 114 then tags the audio, video, and BLUETOOTH fitness device data streams at that moment in time to identify user of computer 304 as sleeping and not contributing to the meeting.

In yet another example embodiment, the user of computer 314 is eating during the online meeting as depicted in FIG. 6C. In analyzing the audio stream data of the online meeting, meeting software 114 determines that the participation level (e.g., the number of times the user of computer 314 speaks), has become less frequent over a period of time and/or speaks with food in his mouth. Additionally, in analyzing the video stream data from the online meeting, meeting software 114 detects that the user of computer 304 is periodically lifting his hand to place food in his mouth. Meeting software 114 also determines that the user of computer 314's mouth is moving in a way that is associated with chewing. Furthermore, meeting software 114 identifies the body heat pattern, or signature of the user of computer 314 as content and not the same as the other meeting participants who are actively participating in the online meeting. In addition to analyzing the audio, video and IR data, meeting software 114 analyzes data from a BLUETOOTH enabled fitness device worn by the user of computer 314 and determines that the heart rate of the user of computer 304 has increased since the user has started eating. Meeting software 114 then tags the audio, video, IR, and BLUETOOTH fitness device data streams at that moment in time to identify user of computer 314 as eating and not contributing to the meeting.

In step 708, meeting software aggregates and summarizes the identified states of the multiple participants to create a single representation of the meeting. For example, meeting software 114 creates a time synchronous stream of outputs that can be used as input or feedback to one or more machine learning algorithms, and to also be used for a later playback of the meeting. In one example embodiment, the aggregated data streams (i.e., a single representation), can show speaker dominance, patterns of eye gaze between co-located participants, participant engagement (e.g., user of computer 304 falling asleep, the user of computer 306 multi-tasking, or the user of computer 314 eating), provide information such as individual focus of attention to help someone on a phone realize what is happening in the room (e.g., so they can see that the facilitator is still concentrating on organizing paperwork, or attending to an urgent call and is not just being silent). The unified representation is a knowledge graph constituting nodes, attributes, and relationships that provides a summary of the important aspects of the participants and their interactions. The nodes include each participant, physical objects in the room, topics, activities/tasks being performed, and so on. The attributes include level of attention, degree of multi-tasking, and so on. Relationships include elements such as disposition of one participant toward another and the relationship between the participants and the topics. There are also attributes on these relationships, such as the level of position disposition and negative disposition. Each value of an attribute in the knowledge graph and the nodes and relationships themselves associated with the history of the streams that contributed to the summary data in the attribute.

Meeting software 114 records and displays the aggregated and summarized data using avatars representing the multiple participants in the multiple rooms as depicted in step 710. For example, meeting software 114 can display the aggregated and summarized identified states of the multiple participants as a single representation of the online meeting on meeting attendance panel 302 as depicted in FIGS. 3 and 6A through 6B. For example, referring again to FIG. 6A, meeting software 114 displays the customized avatars of each meeting participant, wherein the avatars convey the identified state of each meeting participant. The user of computer 118 can see the see the engagement of each meeting participant in the physical space of each meeting participant. For example, the user of computer 118 can see if the meeting participants are approving what is being said for example by nodding, or if the meeting participants are simply not paying attention. In the example embodiment of FIG. 6A, the user of computer 118 can see that the user of computer 314 is focused on typing and not contributing to the meeting.

In the example embodiment of FIG. 6B, meeting software 114 displays the aggregated and summarized state of the user of computer 304, on meeting attendance panel 302, using the customized avatar representing the user of computer 304 in a sleeping state. In another example embodiment, where the user of computer 304 is sharing a physical space (e.g., conference room) with another meeting participant (e.g., user of computer 312), the avatar of the user of computer 312 may convey a distracted state since the user of computer 312 may be frequently looking at the user of computer 304 who is sleeping during the meeting.

Referring again to FIG. 6C, meeting software 114 displays the recognized interplay, exchange, between participants using a collection of machine learning algorithms, wherein the collection of machine learning algorithms captures the different levels of human interaction such as touch, gaze, speech, reference, gesture, reaction, etc. In the example embodiment of FIG. 6C, meeting software 114 identifies the user of computer 314 eating food and not contributing to the discussion. In other example embodiments, the collection of machine learning algorithms monitors the flow of the experience of the meeting participants, and have the system adapt around optimizing, stabilizing, minimizing, maximizing human interaction. For example, meeting software 114 can determine that the user of computer 308 is typically more withdrawn and does not speak up during meetings. Meeting software 114 can then automatically prompt the user of computer 308 via speech, or with a pop up dialogue on a screen for the user of computer 308 to answer, where the user of computer 308 is asked to contribute to the discussion. In another example embodiment, meeting software 114 can notify the host (e.g., the user of computer 118), via speech, or with a pop up dialogue on a screen for the user of computer 118 to see, to ask the user of computer 308 for an opinion on the topic. In terms of optimizing the human interaction, the desired level of human interaction in a meeting varies according to topic and meeting. Therefore, a human participant may set certain levels for certain types of meetings. If there is no human participant, the system can be set to improve the level of human interaction. Instead of one metric, a system can be configured to use various metrics such as amount of speaking. A system can be set up with a number of different categories for each metric such as speaking little, average, or a lot. These values are present as attributes in the knowledge graph unified representation and can also be reflected on the avatar. Data is collected with an update cycle of, for example, 10 seconds. Different metrics may have different configurable update cycles. At the end of the update cycle, features are computed and added to the knowledge graph and used for running a model. While some values are private, others may be shared and displayed.

The machine learning model can be a regression model, or in the case of categories of values for metrics, a logistic regression model. The model can be trained on features extracted from the audio/video streams that are stored in the knowledge graph. Spatial and temporal features can be used for the regression. For example, the speaking amount may be extracted from the audio stream over time. Degree of attention may be extracted from audio and video streams over time (attending a lot) and space (standing up and sitting down, moving around).

Training data may be collected from meetings very similar a target meeting. For example, the features extracted should be measurable in both meetings. If the data is not available then defaults can be set and the model can still be trained, but the model will be less useful. In addition, the number of participants in the meetings should be similar. Models may be developed for two-person meetings, three to five person meetings, and five person and above meetings. For example, the desired type of meeting may be selected and optimal values of metrics assigned and then based upon the differences between the optimal values and the values asserted by the model, various interventions can be expected, such as signaling privately to individuals to “calm down” or suggesting a side meeting between two participants.

FIGS. 8A and 8B are illustrations of a meeting software identifying two meeting participants that are not agreeing on a topic and scheduling a side meeting, in an embodiment in accordance with the present invention. FIG. 9 is a flowchart, generally designated 900, depicting operational steps of a meeting software, on a server within the remote meeting environment of FIG. 1, identifying two meeting participants that are not agreeing on a topic and scheduling a side meeting and removing a detractor of the current meeting, in an embodiment in accordance with the present invention. FIGS. 8A through 9 will now be discussed over the course of the following paragraphs.

Continuing with the previous example embodiment of FIG. 7, the host, on computer 118, is conducting an online meeting with users of computers 304, 306, 308, 310, 312, and 314. Meeting software 114 collects audio, video, and other sensor data from multiple participants in multiple rooms during a meeting as depicted in step 902. For example, meeting software 114 analyzes data of the one or more meeting participants using the audio and video streams, one or more BLUETOOTH enabled devices, such as fitness devices, and one or more IR cameras (not shown).

In step 904, meeting software detects that two participants are disagreeing on a topic. For example, in analyzing the audio streams of the meeting participants, meeting software 114 can recognize and identify the pitch and tone of a meeting participant objecting to a comment spoken by another participant. For example, meeting software 114 can determine if one of the meeting participants is becoming a detractor to the progress in the online meeting as depicted in FIG. 8A. For example, in analyzing the audio stream data of the online meeting, meeting software 114 determines that the participation level (e.g., the number of times the user of computer 304 speaks) has become more frequent over a period of time, and repeatedly directs comments to the user of computer 306. Furthermore, the user of computer 304's pitch has increased and the tone is angry. Additionally, in analyzing the video stream data from the online meeting, meeting software 114 detects that the user of computer 304 is periodically lifting his hands with clenched fists. Meeting software 114 also determines that the user of computer 304's mouth and facial expressions are associated with anger. Furthermore, meeting software 114 identifies the body heat pattern, or signature of the user of computer 304 as being angry. In addition to analyzing the audio, video and IR data, meeting software 114 analyzes data from a BLUETOOTH enabled fitness device worn by the user of computer 304 and determines that the heart rate of the user of computer 304 has increased since the user has started eating. Meeting software 114 then tags the audio, video, IR, and BLUETOOTH fitness device data streams at that moment in time to identify user of computer 304 as disagreeing with the user of computer 306.

Meeting software 114 automatically schedules a side meeting for the two participants to discuss separately as depicted in step 906. For example, meeting software 114 accesses the calendars for the user of computer 304 and the user of computer 306 and determines a future date and time where the issue can be further discussed to prevent the current meeting from progressing. Meeting software 114 then automatically schedules a meeting between the user of computer 304 and the user of computer 306 on the future date and time to discuss the issue. In another example embodiment, meeting software 114 can prompt the host (e.g., user of computer 118), via speech, or with a pop up dialogue on a screen for the host to answer, on whether to schedule the future meeting between the user of computer 304 and the user of computer 306. The host can then manually click on the pop up dialogue to schedule the meeting. In another example embodiment, meeting software 114 can schedule one or more future meetings based on user profile settings for a plurality of meeting participants, wherein the user profile settings are stored on server 102 and can define how meetings can be scheduled. For example, a user may only want to schedule meetings manually and therefore not allow meeting software 114 to access his/her calendar. In another example embodiment, a user would prefer to be asked by meeting software 114 to allow access to his/her calendar prior to scheduling the meeting.

In decision step 908, meeting software 114 determines if there is a detractor in the meeting. If meeting software 114 determines that there is a detractor in the meeting (“Yes” branch, decision step 908), meeting software 114 removes the disruptive participant from the meeting as depicted in step 910. For example, upon scheduling a future meeting between the user of computer 304 and the user of computer 306, meeting software 114 continues to detect anger from the user of computer 304 and that the user of computer 304 is affecting the progress of the meeting. Meeting software 114 can then automatically remove the user of computer 304 from the meeting as depicted in FIG. 8B. In other example embodiments, meeting software 114 may prompt the host (e.g., user of computer 118), via speech, or with a pop up dialogue on a screen for the host to answer, on whether to remove the user of computer 304 from the current meeting. The host can then manually click on the pop up dialogue to remove the user of computer 304 from the current meeting. If meeting software 114 determines that there is not a detractor in the meeting (“No” branch, decision step 908), meeting software 114 skips step 910 as depicted in FIG. 9. In another example embodiment, if there are a small number of viewpoints (e.g., pros and cons) then only the meeting participants involved in the dispute (as measured by interaction intensity/duration/frequency) can be invited to a smaller meeting to “hash out” the differences in viewpoints. More generally, upon detecting a lack of consensus on one or more topics, meeting software 114 can schedule a follow-up meeting involving a subset of the original participants.

In an alternate example embodiment, the present invention can be used to compute the flow of human-to-human interactions between pairs of one or more persons, then suggest possible work partners with whom the one or more persons have NOT interacted with during the meeting. These could also be people that are open to interacting but have not done so potentially because they are distracted by a smartphone during the meeting.

In another alternate example embodiment, the present invention can leverage analyzed data to improve social networking. For example, the user of computer 312 can measure, over a period of time, if the user of computer 312 and the user of computer 314 attend more meetings together, wrote patents and papers together, “friended” one another on social networks, or ended up in the same department at work. This type of system could be used at work parties and in-person social networking events, for example.

In another alternate example embodiment, meeting attendance panel 302 can be replaced with an additional visualization using a petri dish with colored dots representing each meeting participant. As a meeting participant becomes more engaged in the discussion, the colored dot representing the meeting participant migrates more toward the center of the petri dish in proportion to how open and engaged they appear to be with respect to the given person who is speaking.

FIG. 10 depicts a block diagram, generally designated 1000, of components of the server computer executing the meeting software, in an embodiment in accordance with the present invention. It should be appreciated that FIG. 10 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made.

Operating system 1022 and meeting software 1024 are stored in persistent storage 1008 for execution by one or more of the respective computer processors 1004 via one or more memories of memory 1006. In this embodiment, persistent storage 1008 includes a magnetic hard disk drive. Alternatively, or in addition to a magnetic hard disk drive, persistent storage 1008 can include a solid state hard drive, a semiconductor storage device, read-only memory (ROM), erasable programmable read-only memory (EPROM), flash memory, or any other computer readable storage media that is capable of storing program instructions or digital information.

The media used by persistent storage 1008 may also be removable. For example, a removable hard drive may be used for persistent storage 1008. Other examples include optical and magnetic disks, thumb drives, and smart cards that are inserted into a drive for transfer onto another computer readable storage medium that is also part of persistent storage 1008.

Communications unit 1010, in these examples, provides for communications with other data processing systems or devices, including resources of network 116 and computer 118, 304, 306, 308, 310, 312, and 314. In these examples, communications unit 1010 includes one or more network interface cards. Communications unit 1010 may provide communications through the use of either or both physical and wireless communications links. Operating system 1022 and meeting software 1024 may be downloaded to persistent storage 1008 through communications unit 1010.

I/O interface(s) 1012 allows for input and output of data with other devices that may be connected to server computer 1000. For example, I/O interface 1012 may provide a connection to external devices 1018 such as a keyboard, keypad, a touch screen, and/or some other suitable input device. External devices 1018 can also include portable computer readable storage media such as, for example, thumb drives, portable optical or magnetic disks, and memory cards. Software and data used to practice embodiments of the present invention, e.g., operating system 1022 and meeting software 1024, can be stored on such portable computer readable storage media and can be loaded onto persistent storage 1008 via I/O interface(s) 1012. I/O interface(s) 1012 also connect to a display 1020.

Display 1020 provides a mechanism to display data to a user and may be, for example, a computer monitor.
